David,Here's one for your blog and/or anyone you may know who may know about this...

Now I'm a dad of a newborn, my spouse is concerned about our baby being in the same room when I'm playing and it being too loud and damaging his ears. I'm told that adult ears can comfortably deal with sound up to 90 decibels (we could be way off on that, I’m not sure) and that that should be ok for babies. My question is does a saxophone's average decibel level at a comfortable/reasonable distance between player and the another person go above that? I play tenor with a 9 metal otto link tone master... but still in my band I'm not able to really be heard above the guitar amps and drums, etc. without a mic, unlike the trumpet and bone. I need to report back to my baby's momma on this. Any help you could provide would be awesome.Thanks homie!

Thanks for the good question Adam. I was just talking to a friend about this very question. He thought that his Jumbo Java mouthpiece was blowing out his ears. I found some interesting answers to your question. Babies do have more sensitive hearing due to smaller ear canals, the decibel levels that they can take are slightly lower than adults. That said, a babies cry can easily hit 115 on the decibel meter, far above the safe level of 90 decibels. Saxophones aren't much louder than 100 decibels, maybe an Otto Link metal 9 might get you up to 105 decibels if you play triple forte. Adults can take 90 decibels for up to 8 hours safely. If you were to practice for 8 hours at triple forte in the same room with a screaming baby then you both should wear some good earplugs. Hearing loss is very common among musicians, and you would think babies, but there are ways to prevent it. Invest in some good earplugs made for musicians, these will allow you to hear well enough to play while protecting your hearing. If you're playing in the same room with your baby at a mezzo-forte for an hour or two at a time, your baby should be fine as long as you don't blast or play for hours at a time. If you want to be overly cautious you might consider using some wax in your baby's ears and earplugs in yours.Remember that cute little baby of yours can do more damage to your hearing than a jackhammer, so next time you're changing a diaper you may want to think about putting in some earplugs. It seems like you should put earplugs in a crying baby's ears too.Don't take chances with your hearing! Be especially careful when you go into the recording studio. My teacher Ray Brown had his hearing severely damaged by a bad engineer's headphone mix.Don't wait until your ears hurt before taking action. Hearing damage can be almost instanteous or it can be cumulative over years. Either way, musicians can't afford any hearing loss. DCV

Question: Which sound has greater potential to damage your hearing - a baby's cry or a jackhammer? If you answered the former, a baby's cry, you were right, according to information provided by a representative of the Center for Hearing and Health.

At 115 decibels, the sound of a baby's cry can begin to cause hearing damage to a person next to the child after just 15 minutes, reported Dorie Watkins, an industrial audiologist for the Center for Hearing Health. The jackhammer doesn't quite measure up, measuring "only" 105 decibels, she noted; but that level of sound also can cause damage to the inner ear after one hour, according to medical and science standards.

Decibel Levels of Daily Noises

NIOSH has compiled a list of the decibel measurements (dBA) for common noises you might be exposed to each day at home, work or during recreational activities. A decibel is a unit that expresses intensity or power. See what your exposure is to unsafe noises with some of the following examples:

Home:

50 dBA - Refrigerator

50-80 dBA – Electric shaver

50-80 dBA – Electric shaver

60-95 dBA – Hair dryer

75-85 dBA – Flushed toilet

80 dBA – Ringing phone

110 dBA – Crying baby

135 dBA – Noisy squeeze toys

Work:

40 dBA – Quiet office/ library

65-95 dBA – Power lawnmower

90-115 dBA – Subway

105 dBA – Snow blower

120 dBA – Ambulance

140 dBA – Airplane take-off

180 dBA – Rocket launching from pad

Recreation:

70 dBA – Freeway traffic

95-110 dBA – Motorcycle

110 dBA – Car horn

117 dBA – Football game (stadium)

150 dBA – Firecracker

157 dBA – Balloon pop

170 dBA – Shotgun

Other:

0 dBA – Softest level the human can hear

10 dBA – Normal breathing

60 dBA – Normal conversation

110 dBA– Shout in the ear

120 dBA – Thunder

How Much is Too Much?

NIOSH states that the maximum amount of time a person can be exposed to 85 dBA without experiencing hearing damage is 8 hours; this is the average level of noise a person hears every day. However, continuous exposure to 85 dBA beyond the 8-hour limit will cause hearing loss. If a person is exposed to level above 85 dBA, the risk of hearing loss increases in a shorter amount of time. The maximum time allowed for 110 dBA (e.g. a crying baby) is 1 minute 29 seconds. If a person is exposed to a noise that has a measurement of 140 dBA (e.g. airplane departure), immediate inner ear damage would result.

How loud are the activities that you enjoy?

Some Examples of Dangerously Loud Recreational Activities

Noise levels at video arcades can be as high as 110 dBA.

Firecrackers create sound levels from 125 - 155 dBA at an average distance of 10 feet.

Sound levels at live music concerts can be measured at 120 dBA and beyond.

The noise level of gunshots can be measured at 150 dBA -167 dBA and hearing loss can result from just a few shots of a high powered gun, if appropriate hearing protection is not worn.

Noise levels at movie theaters have been measured up to 118 dBA.

Sound levels in health clubs and aerobic studios can be as high as 120 dBA.

Personal stereo systems with headphones produce sounds as loud as 105 - 120 dBA if turned up to maximum levels.

Sound levels at a sporting event can be measured up to 127 dBA.

Motorboats emit sound levels ranging from 85 - 115 dBA.

Motorcycles have been measured at levels ranging from 95 - 120 dBA.

Noise levels of snowmobiles are as high as 99 dBA.

Many children's toys emit sounds which are measured at 135 dBA -150 dBA.

Noise levels from 'Boom Cars' have been measured at 140dBA and beyond."

The nature of blogs and the fact that the Blogger search engine sucks makes it difficult to locate information on Casa Valdez. There are articles that I think are very important for my students that are lost in the archives. I have written about many of the topics that I usually deal with in my private and group lessons. There are some topics that I always teach, and in a certain order. For those students that may not currently have a teacher, or just want to suplement their other studies, I will try to lay out a course of study from the material on this blog. This rough outline is aimed at the Jazz improvisation student. This is simply a suggested course of study, feel free to develop your own.

So we've now finished tracking everything except some last minute bass clarinet and alto flute harmony parts. I recorded one solo that I left out because it was so hard, I didn't want to hold up the entire band until I was happy with it. Well, I'm still not happy with it. I did a shitload of takes and never really got in the groove. Partly because I wasn't really warmed up and partly because the sound was also pretty bad. We were recording in our engineer's small project studio and even though we used the exact same mic setup, the sound came out much brighter and smaller. It's hard to play when you're hearing a weak sound in the cans. I was also going to replace another solo but the sound was so much better in the big studio that we decided to keep the original tracks. This of course wasn't Sean's fault, there's just no way a home studio can come close to the sound of a high end professional studio.

Having great preamps and a top of the line board makes all the difference in the world. At first we were thinking of trying to cut costs by mixing at our engineer's home studio, but we wanted the best sound possible. Pere was talking about having the engineer master the CD on his ProTools HD system to save $500-600 dollars. Mastering is the last phase of the process before pressing and it can really make or break the final sound. Some mastering facilities will do a CD for a flat fee and some charge by the number and length of the tracks. A good mastering facility has very specialized gear that is too expensive to own unless you are in the business of mastering. People say that you should always have a different person master your project than person who mixed it. Mastering is about organizing all your tracks, setting the correct levels, adding the right amount of compression and tweaking the final timbre to create a specific tonal atmosphere. This last operation requires that the mastering engineer has a very clear idea of the sound that you are going for artistically. As with your recording engineer, make sure that the mastering house has done the type of music that you are working with. Rock mastering is a very different game than Jazz mastering. Rock mastering usually compresses the hell out of the sound and cranks up the levels until the waveforms look like bricks.

If you're going to spend several thousand dollars on recording and mixing, then don't be a big weenie and do a half-assed job on the mastering. Here is some more information about mastering from Digital Domain website.

Can't I just mix to DAT?Seven reasons why you need mastering.

Every recording deserves good mastering. When you're through mixing, your work is not finished. Mastering adds polish, it sounds more than just a record...it becomes a work of art. The songs work together seamlessly, their sound can take on a dimensionality and life that enhances even the best mixes. Here are seven reasons why Mastering is needed.

1. Ear FatigueMost music today is produced by recording a multi track tape. The next step is the mixdown. This mixdown may take anywhere from 4 hours to 4 weeks, depending on the producer's predilections, the artist's whims, and the budget. Usually each tune is mixed in isolation. Rarely do you have the luxury to switch and compare the songs as you mix. Some mixes may be done at 2 o'clock in the morning, when ears are fatigued, and some at 12 noon, when ears are fresh. The result: Every mix sounds different, every tune has a different response curve.

2. The Skew of the MonitorsMonitoring speakers. It's amazing when you think about it, but very few studios have accurate monitor systems. Did you know, placing speakers on top of a console creates serious frequency response peaks and dips? A typical control room is so filled with equipment that there's no room to place a monitor system without causing comb-filtering due to acoustic reflections. And though your heart is filled with good intentions, how often do you have time to take your rough mixes around, playing them on systems ranging from boomboxes to cars to audiophile systems? Usually there is no time to see how your music will sound on various systems in different acoustic environments. The result: your mixes are compromised. Some frequencies stand out too much, and others too little.

3. More MeThe producer was supposed to be in charge. He tried to keep the artists out of the mix room. But something went out of control. The producer was gone for the day, or the bassist had a fit of megalomania. Or the artist decided to be his/her own producer. Whatever....all the mixes sound like vocal, or bass, or (fill in appropriate instrument) solos.

4. May I Have Your Order, PleaseWhen mixing, you (the producer) often have no idea what order to put the tunes until after all the mixes are completed. If you physically compile these songs at unity gain, and listen to them one after another, it probably won't sound like "a record." Some tunes will jump out at you, others will be too weak; you may discover (belatedly) that some tunes are too bright or weak in the bass, or that the vocal is a little weak, or that the stereo separation is too narrow. These things actually happen, even after weeks in the studio, and the problems sometimes don't become apparent until the album is assembled in its intended order, or auditioned in a good monitoring environment.

5. The Perspective of another Trained Ear. The Buck Stops Here.The Mastering engineer is the last ear on your music project. He can be an artistic, musical, and technical sounding board for your ideas. Take advantage of his special ear... many beautiful music projects have passed through his studio. You may ask him how he feels about the order of your songs, how they should be spaced, and whether there's anything special that can make them stand out. He'll listen closely to every aspect of your album and may provide suggestions if you're looking for them.

6. Midi MadnessLately it sounds like everyone is using the same samples! Acoustic sounds are coming back in vogue, but perhaps you haven't got the budget to hire the London Symphony. So, you had to compromise by using some samples. But you shouldn't compromise on mastering. Good mastering can bring out the acoustic quality in your samples, increasing your chance of success in a crowded music field.

7. Don't Try This at HomeThe invention of the Digital Audio Workstation (DAW) and the digital mixer is an apparent blessing but really a curse. Many musicians and studios have purchased low cost DAWs and digital mixers because they have been led to believe that sound quality will improve. Unfortunately, it's real easy to misuse this equipment. We've found many DAWs and digital mixers that deteriorate the sound of music, shrink the stereo image and soundstage, and distort the audio. There are several technical reasons for these problems-usually wordlength and jitter are compromised in these low-cost systems. Therefore, we recommend that you protect your audio from damage; use a mastering studio that employs a high-resolution system that enhances rather than deteriorates audio quality. Prepare your tapes properly, and avoid the digital pitfalls. Use the informative articles at theDigital Domain web site as resources to help you avoid audio degradation. When in doubt, take this advice: mix via analog console to DAT or analog tape, and send the original tapes to the mastering house. You'll be glad you did.

Those are only some of the reasons why, inevitably, further mastering work is needed to turn your songs into a master, including: adjusting the levels, spacing the tunes, fine-tuning the fadeouts and fadeins, removing noises, replacing musical mistakes by combining takes (common in direct-to-two track work), equalizing songs to make them brighter or darker, bringing out instruments that (in retrospect) did not seem to come out properly in the mix. Now, take a deep breath and welcome to the world of CD mastering.

from Diskmakers soundlab-

In the recording studio, you record one song at a time, and the focus of the recording or mixing engineer is to make each song great. The result, however, is generally a collection of songs that all peak at different levels and may have different EQs. In the post-production phase (called mastering), a professional engineer unifies the CD by using EQ, compression, and other dynamics processing to give it a consistent sound from track to track.

In addition, post production can raise your album's overall level through the careful use of compression, so your album can compete with any major label release. The mastering engineer also ensures that your music will sound great - whether it's being played through a car stereo, a portable CD player, or a top-of-the-line stereo system. In CD Mastering, the sound of your CD will be optimized, making it sound punchy, warm, and full, while raising the overall level (volume) and highlighting details that aren't already apparent. Post production is also helpful for addressing issues such as "pops," out-of-phase tracks, and overall noise reduction.

A fresh pair of ears can be the difference between a good-sounding CD and a great one. A real advantage of post production is that an unbiased sound professional has the opportunity to evaluate your master and determine how to get the most out of your production. After you've spent weeks or even months in a recording studio listening to your CD over and over again, a fresh pair of ears can put the project into perspective for you and let you know whether or not your CD will benefit from post production. After all, you only have one chance to make your music sound its best. The choice is up to you.

The mastering engineer, to improve your recording, can:

• Raise the overall level.• Even out song levels and EQ individual tracks for cohesion. • Correct minor mix deficiencies with equalization. • Enhance flow by changing the space between tracks. • Eliminate noises between tracks.

Tomorrow I go back into the studio to record for the last time before we start mixing. We'll be in our engineer's the project studio instead of the studio that we recorded the bulk of the tracks in. The first two days of recording at Supernatural Sound cost $900, plus $840 for our engineer. This of course does not include musicians, two of whom we flew in for the session. For the piano tracking we went into Randy Porter's Heavy wood Studio, where Randy tracked his Steinway on five tunes (for $350). Next, at Casa Valdez we had Dan Gaynor play my Casio tone to trigger B4 virtual organ sounds with a PowerBook on four more tunes. Then late one night, after my dogs had gone to sleep, my buddy Damien Mastersen recorded some killer chromatic harmonica on two tracks. Since I want to be right in the same room with the engineer to track my solos (for better communication) we can save some bread by not going back to Supernatural Sound until the final mix. I have to say we got a really great sound at Supernatural, very warm for a digital studio. So far Pere Soto and I have spent almost $4k on this project. The final mixing and mastering will cost another $1420, then the manufacturing costs.

Shit, this had better be good, right?! The CD is something I would have never done had I not co-produced it with Pere. We both are kind of balls-to-the-wall players usually, but this project turned out totally different. It's mostly dreamy romantic Latin music, with a Samba and a Rock-Funk tune thrown in. My grandmother would have even liked it! After years of going to my concerts she once told my mother,"You know, I think that I don't really like Jazz."

One thing I discovered during this recording was that a Royer ribbon mic combined with my clip on SD Systems condenser mic sounds incredible. I've never gotten a better sound in the studio in my life. Each mic compliments the other for a complete full and rich sound. Our engineer Sean Flora has been very easy to work with and really knows what he's doing. He's got great ears, which is crucial. Just being a gear geek doesn't make anyone a good engineer.

Before you choose your engineer make sure he/she has recorded the type of music that you're going to be playing, that they are familiar with the studio that you'll be working in, that they are clear about what their role will be (producer or just engineer), listen to some of the CDs that they have already recorded, give them some CDs that you would like your project to sound like, and have a long talk before the session about how you would like the session to go (schedule, breaks, communication, payment, ect).Be musically prepared! Don't get too distracted by the fact that the clock is ticking and your wallet is draining. Once you start recording think about how you would like your own playing to sound.

One more thing! Always double check to make sure that the piano has been tuned. Not last month either, it's got to be done right before your session. Most of the time the studio will at least split this with you, but not always so be prepared for this extra expense. If you're going to be playing it hard for more than one day you should probably consider getting it touched up before the session is over.

My homeboy Mark Sowlakis just wrote me this email with some very interesting information about how to solve the upper register problems that are so common on Selmer Mark VIs. My alto could definately use something like this. Lee Kramka is one of the most respected repairmen in the Bay Area. Lee's Sax Workx web site

Carlos:Hey man, guess what? I solved the intonation problems on my Mark VI. Well, I didn't solve 'em, but Lee Kramka did. You know how the left hand just gets sharper and sharper as you go up? Well, turns out the by putting a smaller diameter octave pip (the small circular bump with the hole in it on the neck that the octave mechanism sits on), about half the original diameter, drops the second register into incredibly perfect tuning. My octaves are bang on the money now, all the way up, and the sound is fantastic. Lee had been noticing that the newer horns all had smaller diameter octave pips, and thought this would work. As long as your pip is soft soldered it is easy to remove, and mine was. Now this thing tunes even better than the Yamaha and sounds great, it's amazing. He also put some cork in the low C tone hole to bring down the middle d and e, and now it's so great. I'm gonna have him do my tenor as well. Cost was $250 and it was well worth it. I thought I'd pass this on as so many people are chucking their old VI's trying to find better pitch, and this is totally the answer. You might want to post this info you your blog. Also, I have some MP3's here of you that someone passed me, something like Ghengis or thereabouts. Haven't heard them, although I did hear one that was a rehearsal with Charlie Hunter. What was that all about? What's new up there? Markos

Thanks Markos,That does sound like something worth a try. Seems like a better option than cranking open the action on the upper and lower stack to bring down the relative pitch of the palm keys.

You must have MP3s of a four horn band + Charlie Hunter called Quintet D'Gengis (don't ask, only Charlie knew what that meant). That band featured Kenny Brooks on tenor, Adam Beach on bari and Scott Jensen on trumpet, along with me and Charlie. That was Charlies brainchild and his first foray into arranging. I think you may have our demo that was produced by Spearhead's Micheal Franti. We played around the Bay Area in the mid 90's. Keep in touch buddy, David Carlos Valdez

You've definitely got good stuff on your blog!Now, when you take a lesson from Randy, and he talks about, say ii-V-Idim-Imaj7, how do you implement that on your horn?And how do you teach single note players to implement on the horn?Do you have a set of licks that work for I dim to I maj, and work them in each key?I say one can't simply do scales over the patterns...no hip solos come from merely scales (my opinion)and the other example, over Solar:C-7 /C-7 /C-7 / C-7 /We played this:D7alt Cmel- / F7alt Cmel- / Ab7alt Cmel- / Cmel- C-7 /or you can think of it like this:Ebmel- Cmel-/ F#mel- Cmel-/ Amel- Cmel- / Cmelodic- /something you spoke about months ago...or Eb-7 /Ab-7 /Cmaj7How do you implement these substitutions in your playing? Do you come up with licks that "make" the changes, and then practice the licks in twelve keys?As I see it, gotta have structure (i.e., licks, patterns, call it what you will) or scales sound just like scales, nothing more, leading to naive solos that simply don't work.Your thoughts?From sunny Austin,Sammy

Sammy, As a horn player studying with a piano player there is a little translating that I must to to apply certain ideas, but not much. Pianist can certainly flesh out chords substitutions in a way that horn players only dream of. As a horn player applying chord substitutions you need to be clearer than a chordal instrumentalist does. As you move further away from the key of the original changes you need outline the chords in a more direct way. Single note lines can suggest chordal structures strongly enough to create convincing advanced reharms if there is enough clarity in the lines. This doesn't mean playing only digital patterns (for exp. 1,3,5,3) or playing all the notes in every chord. Create strong melodic lines without running scales or chords.

As for licks for I diminished to I maj7 resolutions; take a look at my symmetrical scale article for diminished ideas. Everyone should be familiar resolving from diminished to Major or any other chord. Download the Ray Brown diminished lines that I posted for many of the most common diminished patterns. Write some patterns of your own and learn them in 3 keys, which will get you 12 keys, what a deal!

Patterns should be learned so you can use them as the templates for creating your own lines. I'm not big on learning all your lines in every key. You need to be able to transpose ideas to different keys, but practically speaking if you really learn every new line in all 12 keys then you'll end up repeating yourself like crazy. The listener won't recognize that you played lick X in four different keys, they'll just hear redundancy.

We want to have variety and balance in our solos. Don't play too chordally/vertically OR too linearly/modally, new ideas OR repetition. Don't play too many patterns OR freaky lines. The chord/scale approach needs be balanced with the development of motifs, and the motifs should be drawn from relevant material (the melody, ideas that the rhythm section is comping, your own and others' solo ideas, quotes from other tunes that have similar changes, ect). Remember BALANCE and VARIETY! If ideas are not being developed in your solo then no matter how many cool lines you play your solo will seem static. Focusing on all this theory and reharmonization, chords and scales, can distract you from taking simple melodic ideas and making melodies.

Randy has been trying to wean me away from relying on modes too heavily,"Less Trane, more Bird!". This allows you to outline reharm chords without obliterating the underlying harmony with a hail of notes. After all a scale is much more dense than a chord. Try to choose your chords consciously, don't just randomly play wider intervals. Be prepared to justify the chords that you're outlining.

Randy had me do something that was meant to help melodic awareness. He had me improvise blues choruses, but I had to play the exact same chorus twice in a row. This of course eliminated many unimportant notes and forced me to play stronger, simpler melodies. Another thing Randy suggested was to be aware of when I played a really good idea and then let it breath for a second or two. How will the listeners appreciate your best shit if you never leave them time to digest your amazing lines. How will they hear the true extent of your genius?!

I hope I covered everything you asked about. Thanks for the questions Sammy.

The other day in our lesson Randy Porter showed me and interesting way of a resolving a dominant 7th (b9) chord. He thought it sounded like something that Cedar Walton would play, definately someone worth emulating. It's a very hip yet simple harmonic device.

So over a C7(b9) resolving to a F you would play:A triad, Ab triad, F# triad, then resolve to F

This creates a desending triadic line that leads to the I.

This works for chordal as well as for single line intruments. Just be very clear as you play your triads or triadic line. Major triads are always very strong, able to supercede almost any harmony they are played over. In this case the triads are drawn directly from the chord-scale and descend in stepwise motion, very strong motion indeed.

My friend Tom Pereira sold me the Zimberoff tenor piece I've been playing on. It was re-faced by a guy named Brian Powell and is the nicest tenor mouthpiece I've played. Tom has had many pieces done by Brian and all of them have been vastly improved. Recently I was looking for alto pieces for a few of my students. I really wanted to find something that compared to my battered old hard-rubber slant Link 6. Even though my mouthpiece has seen constant action for the last twenty years and overdue for some maintenance it is still the best sounding alto piece I've ever played. It has a big dark warm sound, it's totally even up and down and still has enough of an edge to cut over any size band. Comparable Slant Links were going for upwards of $600, not in the budget of my students. Tom told me that Charles McPherson was playing on a Meyer copy that Brian Powell had made from a Vandoren V16 blank. I decided to send my Link off to Brain and have him make some copies for my students. The first ones that came back were disappointingly stuffy, edgy and dead. After calling Brian I found that he didn't use the same lay as my piece because he thought that it was too long to be playable. He suggested thinning out the tip and adjusting the inside a bit as well as making the lay longer. The second time I tried the pieces I was floored. They were all smoking! They played exactly like my rare Slant Link 6 except a bit brighter because the rubber was harder than the original Link, this was fine. I had never played anything as good as mine until that moment. The Valdez model V16 Link copies are under $200 and you won't find anything that is even close in that price range. All you need to do to get one is contact Brian and tell him you want the Valdez Link copy, have WWBW send him the V16 that he specifies. In a short time you'll have the best alto piece you ever played in your life, for just $180. I'm going to get one made for myself and then have Brian do some minor work on my original.

Brian does refacing work and his partner Erik does the chamber work, together they call themselves the Mouthpiece Guys. They are true masters of art of mouthpiece making, both having spent many years apprenticing with Ralph Morgan. He is very receptive to the needs of the player and is very reasonable and blazing fast. Check out their endorsement page and the pictures of their work. I cannot recommend these guys too highly.
